The study proposed in this protocol will determine if bioequivalence testing performed for the FDA translates into similar bioequivalence in a population of people with epilepsy when switching among different generics of the anti-epileptic drug (AED). Based on a variety of pharmacokinetic (PK) data and clinical reports of concern, the example anti epilepsy drug (AED) used for this study will be lamotrigine (LTG).
